Elfcups are spring cup fungi that brighten our late winter woodland floor with their attractive fruiting bodies. They grow, often in troops, on rotten fallen twigs of broad-leaved trees. Previously thought to be one species, it has recently been discovered that there are two, only separated by details of the spores. Scarlet Elfcup (Sarcoscypha austriaca) appears to be commoner than Ruby Elfcup (Sarcoscypha coccinea).
